When to use
Node.js

Node.js is a perfect solution for real-time communication apps like chat systems, collaborative tools, and live updates. All thanks to its event-driven, non-blocking architecture. It’s also an excellent choice for building microservices architectures, APIs, and data-intensive apps, handling high concurrency efficiently. Whether applied for building serverless applications, SPAs, streaming services, or IoT systems, Node.js offers flexibility, scalability, and performance to ensure smooth user experiences and manage frequent updates or background tasks.​

From our experience, Node.js works exceptionally well with front-end frameworks like React, which enables seamless communication between client and server. This combination accelerates the development process and automates the deployment. As a result, our can focus on solving the business challenges rather than dealing with intricate backend configurations or scaling issues.​

The synergy between Node.js and React creates high-performance, reliable, and secure applications that can easily scale with your growing business needs, all while optimizing time-to-market and providing the flexibility required for evolving demands.

Architectures we’re
experienced in

Architecture - Microservices architecture
Architecture - Web application

When to use:

In various use cases where flexibility, scalability, and independent development and deployment of components are crucial. We propose this architecture to our clients when their businesses need complex applications with high scalability, load balancing, and isolation failures. This approach also fits the customers who want to achieve rapid and independent development with tech stacks and support real-time execution. Such architecture can also provide benefits like modularity, scalability, agility, technology diversity, and resilience

When to use:

Traditional web app architecture is recommended for a wide range of use cases where the application is accessed and used through web browsers or web-based clients. We propose this architectural approach to our clients when their businesses are working with e-commerce, online retail, social media, online learning, gaming, and other platforms. Traditional web app architecture provides the advantages of cross-platform accessibility, easy updates, centralized data management, and the ability to reach a global audience via web browsers.
